Hengelo-based artist Dimitri Spijk made this skull out of toy soldiers.
Spijk doesn’t appear to have a website, but I found this photo on his Facebook account. The price of the work is 1,000 euro, although it’s unclear if it’s still for sale.
Check Spijk’s Timeline for other works, I already saw a painting (“for the aspiring Spijk collector” as the artist writes) for 50 euro and a birdseed helmet with the text “voer vogels, niet oorlog” (‘feed birds, don’t make war’—in Dutch it is a pun) for 75 euro.
